expand/collapse item About managing Virtual Servers

Before you get started managing Virtual Servers, you should understand the terms Spatial Server, Virtual Server, and ArcIMS service.

You use Virtual Servers to manage Spatial Servers. To help with managing your site, you may want to add additional Virtual Servers. Some common reasons for adding a Virtual Server are:

If you no longer need a Virtual Server, you can remove it. However, before removing a Virtual Server

Only Virtual Servers you added can be deleted. The default Virtual Servers created during installation cannot be deleted.

You can add additional instances to your Spatial Servers through Virtual Server management. In general, the default value of two instances per Spatial Server is the recommendation. You should only increase the number of threads if the CPU for the Spatial Server process appears underutilized. For more information, see Understanding load factors.
